Cash-on-Cash Return Calculator — FAQ

Cash-on-cash return (CoC) measures the annual pre-tax cash flow you earn relative to the total cash you invested in a property — including down payment, closing costs, and setup expenses. It's expressed as a percentage and tells you how efficiently your invested capital is working. A 10% CoC means you're earning $10 for every $100 invested annually.
Most experienced STR investors target 8–15% cash-on-cash return. Returns of 10%+ are considered strong in most markets. Returns below 5% are generally considered weak for the management overhead STR requires. Passive index funds return roughly 7–10% annually, so an Airbnb should beat that threshold to justify active management.
Leverage amplifies both gains and losses. When a property's income return (cap rate) exceeds the cost of debt (mortgage rate), leverage increases your cash-on-cash return — you control more property with less cash. However, if the cap rate falls below your interest rate, leverage drags down returns. Use the comparison toggle to see your leveraged vs all-cash return side by side.
Both serve different purposes. Cap rate is financing-neutral and useful for comparing properties or understanding a market. Cash-on-cash reflects your actual return after debt service and is more relevant to your personal investment outcome. If you're buying with financing, CoC is the metric that determines whether the deal actually works for your situation. See the Cap Rate Calculator for a direct comparison.
The most impactful levers are: (1) increasing ADR through dynamic pricing and strategic amenity upgrades, (2) improving occupancy with better listing optimization, (3) refinancing to a lower interest rate when available, (4) reducing operating expenses like management fees through self-management, and (5) buying at a lower purchase price relative to income.
No. Cash-on-cash return is a pure income metric — it only counts actual cash you receive relative to cash you invested. Property appreciation is excluded. Total return (which includes appreciation) is a different calculation. Many STR investors view CoC as their "floor" return, with appreciation as the bonus that builds long-term wealth.
DSCR loans typically carry interest rates 0.5–1% higher than conventional mortgages, which increases monthly debt service and reduces cash flow. However, they allow investors to scale without W-2 income limitations, and the qualification is based on the property's income rather than personal income. Check your DSCR qualification first using the DSCR Loan Calculator.
Cash-on-cash return measures annual cash income relative to cash invested. ROI (return on investment) is broader and typically includes appreciation, equity paydown, tax benefits, and cash flow over the entire holding period. CoC gives you a snapshot of current performance; ROI gives you the full picture of an investment over time. For STR investors, both metrics matter, but CoC is easier to verify with actual numbers.

Cash-on-Cash Return: The Investor's North Star

Why STR Investors Use Cash-on-Cash Over Cap Rate

Cash-on-cash return is the most direct measure of whether a short-term rental investment is working for you personally. It answers the single most important question in real estate investing: how much of my invested cash does this property return each year? While cap rate ignores financing and treats all investors equally, cash-on-cash return is personal. It changes based on your down payment, your interest rate, and your total cash invested.

For leveraged buyers, cash-on-cash return determines whether you are building wealth or subsidizing a hospitality business. A property with a 7% cap rate looks fine on paper. But if you are putting 25% down at a 7.5% interest rate, the mortgage payments may exceed the NOI, producing a negative cash-on-cash return. In that scenario, you are paying out of pocket every month for a property that may appreciate but is not producing current income.

Short-term rentals complicate the cash-on-cash calculation because of higher startup costs and more variable operating income. Total cash invested must include not just the down payment and closing costs but also furnishing the property ($15,000 to $50,000 depending on size and market), purchasing supplies and linens, professional photography, and any property improvements required before the first guest arrives. Investors who forget startup costs overstate their cash-on-cash return by 15 to 25% in the first year.

Cash-on-Cash Return = Annual Pre-Tax Cash Flow / Total Cash Invested × 100

The Role of Leverage in Cash-on-Cash Returns

Leverage is the defining factor in cash-on-cash returns for real estate investors. When a property's cap rate exceeds the cost of borrowing (the mortgage interest rate), adding leverage increases your cash-on-cash return. When the cap rate is below the cost of borrowing, leverage decreases your return and eventually turns it negative.

A practical example: a property with a 9% cap rate and $80,000 NOI purchased at $890,000. An all-cash buyer earns 9% cash-on-cash, which equals the cap rate. A buyer putting 25% down ($222,500) and borrowing at 7.25% has annual mortgage payments of roughly $54,200. Cash flow after mortgage: $80,000 minus $54,200 equals $25,800. Cash-on-cash on $222,500 invested: 11.6%. Leverage enhanced the return because the cap rate (9%) exceeded the borrowing cost (7.25%).

Run the same example with a 6% cap rate. NOI of $53,400 on the same property. After $54,200 in mortgage payments, cash flow is negative $800. Cash-on-cash is negative. Leverage destroyed returns because the cost of borrowing exceeded the cap rate. This is the leverage trap many STR investors fall into: positive cap rate, negative cash flow. Understanding this relationship helps you quickly evaluate whether a deal requires all-cash to work, or whether financed returns are acceptable.

Leveraged Cash-on-Cash = (NOI - Annual Debt Service) / Total Cash Down Payment × 100

Calculating Total Cash Invested: What Most Investors Miss

The denominator in cash-on-cash return is total cash invested, not just the down payment. Getting this number wrong produces systematically overstated returns. For a short-term rental, total cash invested includes the down payment, closing costs (typically 2 to 5% of purchase price), property furnishing and supplies, professional photography and listing setup, any pre-listing repairs or improvements, the first month of operating expenses during ramp-up, and a working capital reserve.

On a $450,000 property with a 20% down payment, here is a realistic total cash invested breakdown: $90,000 down payment, $9,000 in closing costs (2%), $20,000 in furniture and supplies for a 2-bedroom property, $1,500 for professional photography and setup, $3,000 in repairs, $2,000 for the first month's operating costs, and $5,000 as a working capital reserve. Total cash invested: $130,500, not the $90,000 down payment alone.

Running the cash-on-cash calculation on just the down payment in this example overstates the return by 44%. If the property generates $13,000 in annual cash flow, the down-payment-only calculation shows 14.4%; the full invested-cash calculation shows 9.9%. Both metrics might look acceptable, but the true return is substantially lower. This matters most in year one and two, when you have not yet recouped your startup costs and the property may operate below stabilized occupancy.
